I definitely agree with that because I feel like it’s just a matter of time till they add a Marvel Land at Hollywood Studios so I don’t understand why they chose Epcot but more is more I guess.
Disney is only allowed to use some Marvel characters in Disney World (per their agreement with Universal) so I doubt we'll see a Marvel Land anytime soon.
According to this article, Disney is only allowed to use Marvel characters that Island of Adventure or Universal Studios Florida does not have in the parks.
